Unbing:
Please hold press volume button before plug into socket, then
will remove all been paired receivers.
(Attention: only pairing errors happen, then use this way.)
Receiver
Working voltage: 90-260V
Standby current: 7mA
Working current: 60mA
Working Frequency: 433MHZ
Transmitter
Working voltage: 12V 12V23A*1pcs
Working Frequency: 433MHZ
Standby current: 1μA
Working current: 12mA
RF standby power: 0 dbm
Working range: about 200-300m (on open air)
Failure Analysis and Troubleshooting:
1. Doorbell does not ring
F: receiver host isn’t plugged in or tune mute
A: plug into socket or adjust the volume keys
F: Transmitter battery positive and negative anti-loaded
A: Reinstall the battery
F: Transmitter and receiver pair unsuccessful
A: Re-pair
2.Range become shorter
Please make sure the doorbell away from metal objects.
Buildings, walls, enclosed space will decrease the transmission signal.
Battery voltage or power is not enough will shorten the distance, or misuse ring.
